How do Yin organs differ from Yang organs?

Yin organs are primarily characterized as solid structures that are responsible for storing vital substances such as blood, Qi, essence, and bodily fluids. They include organs like the heart, lungs, kidneys, spleen, and liver, each playing a significant role in maintaining the body's internal environment and balance. Their function revolves around preserving the energy and resources necessary for sustaining life, thus emphasizing their critical role in health and vitality.

In contrast, Yang organs are typically hollow and involved in processes such as digestion, excretion, and movement, which often entails a dynamic and active role in the body. Yang organs include the stomach, intestines, bladder, and gallbladder, which function to process and eliminate substances rather than store them.

Understanding the distinction between Yin and Yang organs is pivotal in Traditional Chinese Medicine, as it helps practitioners diagnose and treat various conditions based on the functionality and nature of these organs.
